Other claims from this paper (13)
- Observation Eucalyptus microtheca provenances differed significantly in total biomass and height.
- Observation Provenances differed significantly in specific leaf area, water-use efficiency and carbon isotope composition.
- Observation Inter-provenance variation was more pronounced under water stress than under well-watered conditions.
- Intervention effect Drought increased the root mass/foliage area ratio and the foliage area/stem cross sectional area ratio.
- Intervention effect Drought increased water-use efficiency and carbon isotope composition.
- Intervention effect Drought decreased total biomass and height.
- Intervention effect Drought decreased transpiration and specific leaf area.
- Association Total biomass and height were positively correlated with mean driest quarter rainfall of the native habitat.
- Association Transpiration and SLA were positively correlated with mean driest quarter rainfall of the native habitat.
- Association Root mass/foliage area ratio and foliage area/stem cross sectional area ratio were negatively correlated with mean driest quarter rainfall of the native habitat.
- Association WUE and carbon isotope composition were negatively correlated with mean driest quarter rainfall of the native habitat.
- Observation Provenances from dry areas and trees grown under drought had smaller transpiration and shorter hydraulic pathway length.
- Mechanism The authors suggest the root to leaf water potential gradient might be smaller in provenances from dry areas and in drought-stressed trees.
